Anthony Zimpfer completed Ballotpedia's Candidate Connection survey in 2025. The survey questions appear in bold and are followed by Zimpfer's responses. Candidates are asked three required questions for this survey, but they may answer additional optional questions as well.
| Collapse all
- Extensive campaign finance reform. When politicians answer to voters instead of donors, real change becomes possible.
- Medicare for All is an investment in a healthier nation, and in the freedom to adapt and thrive in a new economy.
- Urgent climate action is essential to secure a healthy planet and a strong future for the next generation.
At the core of all of this is a simple belief: government should work for everyday people and reflect our shared American values of fairness, responsibility, and opportunity.
